一种石油化工用转子泵
摘要：
本发明属于泵技术领域，具体的说是一种石油化工用转子泵，包括壳体、转子、转动盘和一号滑块；所述壳体为圆柱形，壳体的内壁设置一组圆弧凸块，所述转子位于壳体内部，转子的形状与圆弧凸块相配合；所述转子内部设有一号滑块；所述一号滑块外围设有螺旋槽；所述转动盘位于转子内部，转动盘的内部设置一组螺旋导块；所述螺旋导块配合一号滑块中的螺纹槽使得一号滑块在转子外围的滑槽中滑动。通过转动盘内部的螺旋导块与转子内部一号滑块的螺旋槽啮合转动，一号滑块收到转子内，改变转子与石油的接触面积，进而控制了转子转得的油的量。
摘要（英）：

The invention belongs to the technical field of pumps, and particularly relates to a rotor pump for petrochemical engineering. The rotor pump comprises a shell, a rotor, a rotating disc and first sliding blocks; the shell is cylindrical; a group of arc convex blocks are arranged on the inner wall of the shell; the rotor is located in the shell and is matched with the arc convex blocks in shape; the first sliding blocks are arranged in the rotor; spiral grooves are formed in the peripheries of the first sliding blocks; the rotating disc is located in the rotor; and a group of spiral guide blocks are arranged in the rotating disc and are matched with spiral grooves in the first sliding blocks so as to enable the first sliding blocks to slide in a sliding groove in the periphery of the rotor.According to the rotor pump, the spiral guide blocks in the rotating disc mesh with the spiral grooves of the first sliding blocks in the rotor to rotate, the first sliding blocks are retracted intothe rotor, the contact area between the rotor and oil is changed, and therefore the amount of the oil transferred by the rotor is controlled.
